More than likely passed to the pups from the ovcharka part in your female.I have a pyr/maremma male and a pyr/anatolian/ akbash/ovcharka female. They had pups last year and I ended up with 2 that were black and white. Here is a picture of one of them.
There are a lot of "accidents" out there and people are less than honest and like to pass off dogs as being "rare", special breeding-highly valuable etc. etc. .
I did google this too, and it was as I figured... but out of respect for our poster and staying on subject, I will say with a big smile.... NO COMMENT.
BTW the pup is cute
